Answer 1

To load image in Swift 3.0 from application document directory in a UIWebView with his expected ratio -

if let dir = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first {
            let path = dir.appendingPathComponent(imageName)
            
            
            
        let fullHTML = "" +
            "" +
            "" +
            "" +
            "" +
            "" +
            "" +
            " "
            
            imgWbView.loadHTMLString(fullHTML, baseURL: nil)
}
